Slope Compensation works as a look-ahead for the vehicle. Slope Compensation helps aids in moving the vehicle up the hill to keep the implement on the guidance line.

  • 0—2 degrees - Slope Compensation may not be needed
  • 2—5 degrees - Use of Slope Compensation is recommended to provide moderate amount of machine correction
  • Greater than 5 degrees - Use of Slope Compensation is recommended

NOTE: If slope compensation value is above 4.00 after calibration, calibrate again. Recalibration is recommended to verify a consistent slope compensation value. If a consistent value is not achieved, review the slope compensation guidelines.

General Slope Compensation Guidelines:

  1. iGuide must be active to calibrate
  2. Calibrate at operating speed with implement at operating depth
  3. Do not calibrate when:
    • Roll angle is less than 2 degrees
    • Direction of roll angle may change
    • On tight curves
    • A line acquisition is occurring
  4. Slope compensation may not be required on slopes less than 5 degrees
  5. Stop calibration after calibrated slope compensation value stabilizes
